15 people working 5 hours per day can make 30 units of a product in 10 days. Assuming all other factors remain constant and people of the same efficiency are used to make the same products, in how many days can 10 people make 10 units of the product if each of them works 10 hours per day?

Answers

It will take 10 people working 10 hours per day about 2.5 days to make 10 units of the product.

From the statement of the question; 15 people working 5 hours per day can make 30 units of a product in 10 days. Hence, the number of units that can be made in a day is;

Number of units per day = (15*5*10)/30

= 25 units/day

Now; if 10 people make 10 units, working 10 hours per day, it will take them x number of days.

x =  (25*10)/10*10

x = 2.5 days

Lisa purchased a hat for $10, a purse for $20, and a book for $23.The sales-tax rate was 7.2 percent. What was the total amount she paid?

Answers

From information given Lisa bought three items.

10 + 20 + 23 = 53 dollars ( which is total pre- tax cost)

The sales tax rate is at 7.2% . Value of this tax in dollars will be:

7.2 % of 53 →  (7.2 / 100) × 53  →  0.072 × 53 =  3.816

So the tax rate value is 3.816

Total cost of items will be 53 + 3.816 =  56. 816

Rounded off  to the nearest cent 56.816   =  56.80

Therefore Lisa paid a total of $ 56.80
